Abstract

The invention refers to a delivery system (1) for delivering a self-expanding scent (2) to a predetermined location in a body lumen, the delivery system comprising: - a catheter body (3) having proximal and distal ends (5, 4), the catheter body (3) being adapted for transporting the stent (2) to a predetermined site in said body lumen for deployment; - the stent (2) being carried by said catheter body (3) near the distal end (4); - a retractable outer sheath (6) surrounding the scent (2) and containing the scent (2) in a delivery configuration where the stent (2) has a reduced radius along its entire axial length (L E); and - a proximal retraction handle (7) connected to the proximal end (5) of the catheter body (3), wherein: - the sheath (6) comprises: - an outer tube (8) having a distal end portion (9) surrounding the stent (2) along its entire length (L E) and having a proximal end portion (10) being connected to the retraction handle (7); and - a separate inner tube (11) being disposed concentrically within the outer tube (8) and having a distal end portion (12) surrounding the scent (2) only along a part (L p) of its entire length (L E).

Claims (9)

1. A delivery system (1) for delivering a self-expanding stent (2) to a predetermined location in a body lumen, the delivery system comprising:

a catheter body (3) having proximal and distal ends (5, 4), the catheter body (3) being adapted for transporting the stent (2) to a predetermined site in said body lumen for deployment;

- the stent (2) being carried by said catheter body {3) near the distal end (4);
- a retractable outer sheath (6) surrounding the stent (2) and containing the stent (2) in a delivery configuration where the stent (2) has a reduced radius along its entire axial length (L E) ; and - a proximal retraction handle (7) connected to the proximal end (5) of the catheter body (3), being characte- rized in:
- that the sheath (6) comprises:
- an outer tube (8) having a distal end portion (9) surrounding the stent (2) along its entire length (L E) and having a proximal end portion (10) being connected to the retraction handle (7); and - a separate inner tube (11) being disposed concentrically within the outer tube (8) and having an end portion (12) surrounding the stent (2) only along a part (L p) of its entire length (L E).
2. Delivery system according to claim 1, being characterized in that said handle (7) comprises a retraction tube (13) being connected at its distal end (14) to said proximal end portion (10) of said outer tube (8).
3. Delivery system according to claim 2, being characterized in that said retraction tube (13) comprises a stop member (15) at its distal end (14).
4. Delivery system according to claim 2 or 3 being characte-rized in that said retraction tube (13) concentrically surrounds said proximal end (5) of said catheter body (3) and a proximal end portion (16) of said inner tube (11).
5. Delivery system according to claim 4, being characterized in that said inner tube (11) comprises a stop member (17) at its proximal end portion (16) that is adapted to be engaged with said stop member (15) of said retraction tube (13) upon retraction of said handle (7).
6. Delivery system according to one of claims 1 to 5, being characterized in that said inner tube (11) surrounds said stent (2) along about 40 % to 60 % of its entire length (LE).
7. Delivery system according to one of claims 1 to 6, being characterized in that said stent (2) is configured as a stent graft or a covered stent.
8. Delivery system according to one of claims 1 to 7, being characterized in that said separate inner tube (11) is fixed to a shaft (18) of catheter body (3).
9. Delivery system according to one of claims 1 to 8, being characterized in that said end portion (12) of inner tube (11) is the distal end portion of inner tube (11).
